Vascular Stenting

Vascular stenting is a great method of treatment for all kinds of vascular problems like renovascular hypertension. When you hear about vascular stenting, you tend to think about the cardiovascular system. Vascular stenting is a method of treatment for all kinds of vascular problems, even those in the peripheral blood vessels. There are blood vessels all over the body to supply you with blood. When the blood vessels become narrow, it affects blood flow. You run the risk of organ and tissue damage. A lack of blood flow to the kidneys is dangerous and has negative effects on your health. There are many forms of treatment, but stenting is one that is very helpful and can prevent more serious problems.

Renal Arteries

There are arteries all throughout the body. Arteries are the largest of the blood vessels. They carry blood to some of the most important parts of the body. There are arteries to supply the brain, heart, and lungs. There are also arteries that supply blood to the legs and arms. The renal artery supplies blood to the kidneys. There are two renal arteries because there are two kidneys. The renal arteries have to function properly for the kidneys to function properly. If there are problems with the renal arteries, you will also have problems with the kidneys.

Vascular Problems

The vascular system is subject to all kinds of problems. Two problems that go hand in hand is atherosclerosis and stenosis. Atherosclerosis is a hardening of the arteries, typically caused by cholesterol buildup. When that happens, there is a subsequent issue called stenosis. The arteries become narrow. When the arteries become narrow, there is less blood flow. Other problems could also occur like clotting. When it comes to the kidneys, renal artery dysfunction affects more than just your kidneys. When your kidneys are affected, the blood may not get filtered properly and on top of that, your blood pressure is affected.

Vascular Stenting Procedure

Vascular stenting is a surgical process. It is a minimally invasive surgery. You will be put under general anesthesia first. The purpose of the procedure is to improve blood flow. The first step is the use of fluoroscopy. The surgeon turns on an X-ray beam that projects light that passes through the blood vessels. This light projection allows the surgeon to see inside the blood vessel. The next step is the addition of the catheter. A catheter is a very thin tube that is also long. The catheter is placed into the renal artery. It is pushed through the artery until it reaches the right position. Once in the right place, there is a balloon that is inflated. It is not a balloon-like you would give someone for a birthday. It is a very small balloon. The purpose of the balloon inflation is to open the blood vessel. Once the blood vessel opens up, the balloon is deflated and removed. The next step is the addition of the stent. The stent is placed in the catheter. The stent, although it sounds like sticks, is a small wire mesh tube. The stent is put inside the artery permanently. The stent keeps the artery open. The stent may be bare or covered. The surgeon will determine which stent is best for you.

After the Procedure

Once the procedure is over, you will be monitored. Some people do not go under general anesthesia. Some have local anesthesia and are awake during the process. Either way, you will need to be monitored when the procedure is over. A few afters after the procedure, the surgeon will check the site of the catheter insertion. Bleeding and swelling will be monitored very closely. Sometimes you are given medicine to relax the arteries and prevent spasms. You may also urinate a lot after the procedure. For the first 24 hours, you should take it easy. Drinking a lot of water is very important. You do not want to get dehydrated. Do not lift heavy objects and do not get involved in risky behavior like drinking and smoking. Be aware of any bleeding, discoloration, or pain. If you notice any abnormal changes, contact your physician right away. Pain meds are usually prescribed to help with discomfort.

Vascular stenting is a short procedure that does not require a lot of recovery time. When you have vascular diseases, stenting can help treat the problem before your issue becomes serious. When vascular problems affect the kidneys, it should be treated right away. When the kidneys are not getting enough blood, it has a major impact on your blood pressure. Over time, it will affect kidney function. When the problem is ongoing, the kidneys will begin to fail. If you are in need of vascular stenting, you should go for it. It is minimally invasive and does not require a lot of recovery time.
